Definitions

  • the invention concerns a drive system for individually driving the two driven wheels of a driven wheel pair or suchlike for a vehicle.
  • a further disadvantage is considered to be that for reasons of available space, it is often difficult to fit next to one another two drive aggregates arranged out of alignment with one another.
  • Each consists of a drive motor, transmission arrangement and wheel in the direction of the rotation axis of the driven wheel pair and to design a driven axle arrangement for them.
  • the drive system comprises two continuously variable drive machines each of which is in drive connection, via a transmission arrangement, with an associated driven wheel or the like.
  • the transmission arrangement comprises two respective transmission units arranged one behind the other.
  • One of the transmission units being designed as a shift transmission and the other transmission unit as a bevel gear transmission with a fixed ratio.
  • This drive train solves both of the technical problems outlined in that for each driven wheel two transmission units are used.
  • One of the transmission units is designed to enable the transmission ratio to be changed and the other transmission unit to improve the installation circumstances.
  • two-speed or drive torque ranges can be preselected, while the bevel gear transmission makes it possible to arrange the drive machines and, if necessary, one of the two transmission units perpendicular to the rotational axis of the driven wheels.
  • the respective shift transmission of the transmission units is made as a two-stage planetary gearset in which the sun gear wheel is connected to a drive input shaft and the planetary gear carrier to a drive output shaft.
  • a ring gear wheel of this planetary transmission can optionally be locked in a rotationally fixed manner or coupled to the drive output shaft.
  • the shift transmission is arranged downstream from the drive machine and the bevel gear transmission downstream from that transmission.
  • the purpose of the invention is to provide a drive system of the type just outlined, which enables the final speed or drive torque to be varied and which is easier to fit into a vehicle.
  • the drive system should be designed such that it can be used in different vehicle types, fitting space situations and distances of the drive aggregates above the ground, with only slight structural alterations using most of the same drive system components.
  • the invention is based on recognition of the objectives can be realized by relatively simple constructive measures by distributing the above mentioned, part objectives on which the invention is based between two transmission units; one of these transmission units is designed to enable variation of the transmission ratio while the other is designed to improve the installation requirements.
  • Almost universal utility in different vehicle types is achieved by designing the transmission units in a particular manner.
  • the starting point of the invention is a drive system for individually driving two driven wheels of a driven wheel pair or the like for a vehicle comprising two continuously variable drive motors each of which is drivingly connected, via a transmission arrangement, with an associated driven wheel or the like.
  • a respective transmission arrangement comprising two transmission units; one of these being a shift transmission and the other transmission unit being bevel gear transmission comprising a spur gearset and a bevel gearset.
  • the shift transmission allows the transmission drive ratio to be varied, while the bevel gear transmission enables the drive shafts of the drive motors to be transversely arranged with respect to the rotational axis of the driven wheels.
  • the spur gearset in each case makes it possible to position the drive shafts of the respective transmission units higher or lower, depending on the type of vehicle.
  • varying the arrangement of the bevel gears of the bevel gear transmission, relative to one another enables constructively easy adjustment of the inclination of the respective drive motor and shift transmission, relative to the longitudinal axis of the vehicle, in relation to a horizontal plane and of the drive output angle of the output shafts of the transmission units so that this drive system can be used with a largely identical component configuration for different vehicle types.
  • the bevel gear transmission enables the drive motor and, if necessary, one of the two transmission units to be arranged perpendicularly to the rotation axis of the driven wheels, which considerably improves the fitting possibilities as will be illustrated with reference to example embodiments.
  • the spur gear stage on the drive output side then enables the spatial orientation of the transmission output to be adjusted within a wide range and the geometrical orientation of the drive motors and the transmissions transverse to the vehicle's longitudinal axis also to be varied.
  • the shift transmission is a two-stage, planetary gearset whose sun gear wheel is connected to a drive input shaft, whose planetary gear carrier is drivingly connected with a drive output shaft and whose ring gear wheel can optionally be locked in a rotationally fixed manner or coupled to the drive output shaft.
  • Planetary gearsets allow relatively large transmission ratios while being of a compact structure.
  • a shift enables a large transmission ratio changes, again with little structural complexity by way of the ring gear wheel which can optionally be locked or coupled to the drive output shaft and, therefore, to the planetary gear carrier in fixed connection with it.
  • the shift transmission of each transmission unit is arranged downstream from the drive motor and the bevel gear transmission is arranged downstream from the shift transmission.
  • the drive motors are arranged one behind the other, in the direction of the vehicle's longitudinal axis.
  • the bevel gearset of the bevel gear transmission has a first bevel gear, which is connected in a rotationally fixed manner with the output shaft of the shift transmission and which meshes with a second bevel gear, while the second bevel gear is connected in a rotationally fixed manner or is integral with a first spur gear which meshes with a second spur gear.
  • the latter is connected in a rotationally fixed manner to the output shaft of the respective transmission arrangement.
  • the spur gearset of the bevel gear transmission comprises a first spur gear which is connected in a rotationally fixed manner to the drive output shaft of the shift transmission and which meshes with a second spur gear.
  • This second spur gear is connected in a rotationally fixed manner or is integral with a first bevel gear, which meshes with a second bevel gear connected in a rotationally fixed manner to the output shaft of the respective transmission arrangement.
  • the drive shafts of the two drive motors are arranged substantially perpendicular to the rotational axis of the driven wheel pair and the orientations of the respective bevel gear transmissions can be varied essentially by 90 degrees.
  • Another further embodiment provides that the output shaft of at least one shift transmission and the drive shaft of the associated drive motor are orientated to be at an angle to the vehicle's longitudinal axis in relation to a horizontal plane, whereby the ground clearance of these drive aggregates can be made larger.
  • the drive system is axially shorter if the output shaft of at least one shift transmission and the drive shaft of the associated drive motor are perpendicularly orientated to the longitudinal axis of the vehicle. Further axial shortening and a reduction of the width of the drive system can be achieved if the output drive shafts of the drive aggregates are also arranged perpendicular to the transverse axis of the vehicle.
  • Another further embodiment provides that the rotational axis of the combined bevel and spur gear lies in a horizontal plane different than that of the rotational axis of the output shaft of the respective transmission arrangement.
  • This embodiment enables the drive output of the transmission arrangement to be located in the vehicle comparatively low, down toward the road so that when the driven wheels of the vehicle are driven by way of synchronous articulated shafts, the maximum deflection angle of the latter can be used to realize particularly large spring deflections.
  • the drive motors and the transmissions are arranged essentially one behind another or essentially next to one another.
  • the drive system is comparatively narrow and long in the vehicle's longitudinal direction whereas, according to the second embodiment, the drive system can be made comparatively short, but wider.
  • the drive motors are arranged above the rotational axis of the output shafts of the transmission arrangement in order to obtain optimum ground clearance.
  • the drive shafts of the drive motors are, in each case, arranged perpendicular to the rotational axis of the driven wheel pair and the respective bevel gear transmission has a deflection angle essentially of 90 degrees.
  • the drive motors can be arranged along the vehicle's longitudinal axis ahead of and behind the rotation axis of the driven wheel pair so that the transmission arrangements are positioned, facing one another, close to the vehicle's longitudinal axis and can be connected by way of relatively long articulated shafts to driven wheels with individual spring suspensions.
  • the drive motors are preferably electric motors whose speed can be regulated in a simple manner.
  • the drive system is preferably used in vehicles in which the driven wheels have individual spring suspensions.
  • the wheels are connected by articulated shafts to the associated drive motors or the transmission units arranged downstream from the latter.
  • FIG. 1 is a drive system with the drive aggregates arranged in the longitudinal direction of the vehicle in which a respective shift transmission and a bevel gear transmission with a spur gear stage are arranged downstream from each drive motor,
  • FIG. 2 is a drive system, as in FIG. 1 , but with the drive aggregates in a vertical arrangement
  • FIG. 3 is a schematic side view of a drive system from a point of view normal to the longitudinal direction of the vehicle;
  • FIG. 4 is a schematic top view of a drive system from a point of view normal to the longitudinal direction of the vehicle;
  • FIG. 5 is another schematic side view of a drive system from a point of view normal to the longitudinal direction of the vehicle.
  • FIG. 6 is a view of a portion of the drive system from a point of view along the longitudinal direction of the vehicle.
  • the drive system shown in FIG. 1 , comprises a first drive motor 2 associated with a first driven wheel 4 and a second drive motor 6 associated with a second driven wheel 8 .
  • a two-stage, shift transmission 10 in the form of a planetary gearset.
  • the sun gear 12 of the transmission 10 is connected with a drive input shaft 14 of the drive motor 2 and is engaged with several planetary gears 18 arranged on a planetary gear carrier 16 ; these being engaged on the other side with the inner teeth of a ring gear wheel 20 .
  • the two drive motors 2 , 6 and the respective transmissions arranged after them are arranged essentially one behind the other in a horizontal plane in a vehicle (not illustrated further).
  • the plane also contains the longitudinal axis 73 of the vehicle.
  • the planetary gear carrier 16 is connected to a drive output shaft 22 which carries a bevel gear 24 at its free end that is engaged with a bevel gear 26 .
  • this latter bevel gear 26 is connected in a rotationally fixed manner or is integral with a spur gear 29 , which is connected to a spur gear 31 at the transmission end of an output shaft 28 of the transmission arrangement.
  • This output shaft 28 is drivingly connected with the first driven wheel 4 via an articulated shaft 30 .
  • the articulated shaft 30 , 46 enables a spring-loaded suspension 80 , 81 of the driven wheel 4 , 8 in a manner generally known and is not explained further.
  • the driven wheel 4 is driven by the articulated shaft 30 , via an additional planetary gearset 32 , also as known in itself and, therefore, not explained again here.
  • the transmission 10 is made as a two-stage shift transmission.
  • the ring gear 20 can optionally be coupled, via a shift pinion 34 , either with a shift gear wheel 36 which is fixed on the drive shaft 22 , as shown in FIG. 1 , or with an array of locking teeth 38 fixedly arranged in the transmission housing.
  • the planetary gear carrier 16 and the ring gear wheel 20 are coupled in a rotationally fixed manner with one another.
  • the planetary gears 18 do not rotate relative to the ring gear 20 , nor relative to the sun gear 12 either so that the drive output shaft 22 rotates at the same speed as the drive input shaft 14 .
  • the ring gear 20 When the ring gear 20 is coupled by the shift pinion 34 to the locking teeth 38 , the ring gear 20 is locked, relative to the housing, and the planetary gears 18 rotate on the inner teeth of the ring gear 20 so that the speed of the drive input shaft 14 is converted, in a known way, into a speed of the drive output shaft 22 that is different from it.
  • the drive system associated with the second driven wheel 8 is made in the same way as the drive system for the driven wheel 4 , described above. It comprises a two-stage shift transmission 40 made as a planetary gearset, arranged downstream from the second drive motor 6 with a drive output shaft 49 , a bevel gear transmission formed of bevel gears 42 and 44 , a spur gear stage 41 on the bevel gear 44 and, meshing with the last-mentioned spur gear stage 41 , a spur gear 43 rotationally attached in a fixed manner onto an output shaft 45 of the second transmission arrangement.
  • This output shaft 45 is in active driving connection with an articulated shaft 46 such that a further planetary gearset 48 , associated with the second driven wheel 8 , can be driven.
  • the two driven wheels 4 and 8 are driven independently of one another by their respective associated drive motors 2 and 6 . No power transfer takes place from one side to the other. Accordingly, the speed or drive torque regulation in the vehicle takes place by way of the shift transmissions 10 , 40 .
  • the speed of one of the two driven wheels 4 and/or 8 is slowed or accelerated by correspondingly regulating the associated drive motor 2 , 6 so that the vehicle drives in a curved path as a result of the different speeds of the driven wheels.
  • the respective drive motors 2 , 6 and their associated transmissions 10 , 40 can be adjusted through an angle, so to speak out of the plane of the paper in FIG. 1 , relative to a horizontal plane 76 containing the longitudinal axis 73 of the vehicle as seen in FIG. 3 , since the point of engagement, between the respective bevel gear 24 , 42 of the shift transmission 10 , 40 connected with the output shaft 22 , 49 and the associated bevel gear 26 , 44 of a bevel gear transmission 70 , 72 , can be varied.
  • the engagement point of the respective gears 24 and 26 or 42 and 44 is designed in such manner that the engagement point adopts the position desired on the gear teeth about the circumference of the bevel gear 26 and 44 , respectively, as appropriate for the type of vehicle in question.
  • This measure makes it possible to increase the ground clearance of the drive motors, when designing the drive system.
  • the drive output angle of the output shafts 28 and 45 of the two transmission arrangements can be adjusted during construction by the aforesaid adjustment of the point of engagement.
  • the drive output angle is chosen such that the maximum possible deflection angle of an associated synchronous articulated shaft 30 , 46 can be used in an optimum manner.
  • FIG. 1 discloses that, in this drive system, even the location of the output shafts 28 and 45 of the transmission arrangements can be modified in a manner specific for the type of vehicle. This can be done because the engagement point of the respective spur gear 31 , 43 of the respective drive output shaft 28 , 45 with the associated spur gear 29 , 41 of the bevel gear transmission 70 , 72 can be varied. Accordingly, this design measure enables the rotational axes of the two output shafts 28 and 45 of the transmission units to be raised or lowered relative to the road and to the rotational axes of the combined bevel and spur gears 26 , 29 and 41 , 44 , respectively.
  • FIG. 2 shows a drive system, similar to FIG. 1 , but is represented as viewed in the vehicle's longitudinal direction 73 .
  • the two drive motors 2 , 6 and the shift transmissions 10 , 40 are fitted vertically in the vehicle instead of horizontally as in FIG. 1 . Consequently, the output shafts 22 and 49 of the transmission arrangements are essentially perpendicular to the road.
  • the drive aggregates depending on the structural space situation in the vehicle concerned, they can be arranged, in relation to the longitudinal direction of the vehicle, either axially one behind the other or, as shown in FIG. 2 , next to one another in the vehicle.
  • the two shift transmissions 10 and 40 have on their output side respective spur gears 50 and 60 , which are connected in a rotational fixed manner to the associated output shafts 22 , 49 of the transmission.
  • These spur gears 50 , 60 respectively mesh with associated spur gears 52 and 62 of bevel gear transmissions 54 and 64 with a fixed transmission ratio.
  • the spur gears 52 and 62 are connected in a rotationally fixed manner or are integral with respective bevel gears 53 and 68 .
  • the bevel gears 53 and 68 mesh, respectively, with an associated other bevel gear 56 and 66 , each of these latter being coupled in a rotationally fixed manner to one or the other of the output shafts 28 and 45 . From there, the torque is passed onto the two driven wheels 4 and 8 by way of associated articulated shafts 30 and 46 , respectively, in the manner described earlier.
  • FIG. 2 shows that in this vertical arrangement of the combination consisting of drive motor 2 , 6 and shift transmission 10 , 40 , their drive input shafts 14 and drive output shafts 22 , 49 can be arranged in a vehicle at an angle which, in relation to the horizontal plane 76 , is not perpendicular to the longitudinal axis 73 of the vehicle.
  • the engagement point of the respective gears 53 and 56 and 66 and 68 is constructively varied in such a manner that the point adopts the position desired, for the vehicle type concerned, on the gear teeth about the circumference of the bevel gear 56 , 66 connected to the input shaft 28 , 45 .
  • the output shaft 22 , 49 of at least one shift transmission 10 , 40 and the drive input shaft 14 of the associated drive motor 2 , 6 are orientated at an inclination to the longitudinal axis 73 of the vehicle and to a horizontal plane 76 .
  • the output shaft 22 , 49 of at least one shift transmission 10 , 40 and the drive input shaft 14 of the associated drive motor 2 , 6 are orientated perpendicularly to the vehicle's longitudinal axis 73 and to the horizontal plane 76 .
  • the rotation axis 58 , 74 of the combined bevel and spur gear 26 , 29 ; 41 , 44 , as shown in FIG. 6 lies in a horizontal plane 78 different from that of the rotational axis 82 of the output shaft 28 , 45 of the respective transmission arrangement.
